Sintered Porous Metal Filter Tube & Cartridge is used primarily for filtering gases, steam, solvents and process liquids through rigid sintered stainless powder tubes that can be back-flushed and reused for years. This page lists the industries and assemblies where it is specified, the selection criteria that matter for each application, handling and installation practice, and the cases where a different mesh, screen or filter type is the correct choice. It is supplied to ISO 4003 / ISO 4022 / ASTM E128.
Typical Applications for Sintered Porous Metal Filter Tube & Cartridge
Where Sintered Porous Metal Filter Tube & Cartridge is specified and bought:
- Chemical & petrochemical: catalyst recovery and solvent polishing filters.
- Gas & steam: process gas, nitrogen and clean steam filtration.
- Pharmaceutical & food: sterile vent and steam filters with welded fittings.
- Semiconductor & instrumentation: gas line and sampling filters.
How to Specify Sintered Porous Metal Filter Tube & Cartridge for Your Application
- Micron rating: From 0.5 to 100 µm; specify liquid or gas rating, which differ for the same element.
- Dimensions & wall: OD, length and wall thickness set flow and strength.
- End fittings: Welded caps, NPT, DOE, 222/226 O-ring or flanged ends.
- Standard: Quote ISO 4003 / ISO 4022 / ASTM E128 and the size designation from the table on the product page, plus any value you changed in the technical drawing.
Handling & Installation Practice
- Back-pulse or back-flush when differential pressure reaches the design limit.
- Clean ultrasonically or by solvent, then verify bubble point.
Common Selection Mistakes with Sintered Porous Metal Filter Tube & Cartridge
- Specifying a micron rating without the permeability or flow rate.
- Over-tightening threaded ends, which cracks the porous body.
Where Sintered Porous Metal Filter Tube & Cartridge Is Not the Right Choice
Not economical for high-volume, low-value water filtration where disposable cartridges are cheaper.
